Waterglip kills: Judge rejects charges in the signal's capping

Wyandotte County District Court Judge Robert Burns joined the case on Friday against three drivers and two companies with Schlitterbahn, the 17-story attraction, according to court documents obtained by CNN.

Burns said the grand jury was "irretrievably infected by the launch of illegal evidence" by the Kansas Attorney General's office. Court documents say the defendants complained to the grand jury have shown a "highly dramatic" television program about the incident and are told from an unrelated death in another water park.

The slide is called Verruckt, which means "insane" in German. It was certified in 2014 as the world's tallest water slide.

Caleb Schwab packed it in a raft with two women. He was attacked when the float got moving and trapped overhead hoops and network on the slide, investigators said.

The boy was Kansas State Secretary Scott Schwab, who was a state representative at the time.

Kansas Attorney General Derek Schmidt said he was disappointed with the verdict that he said the state would take a new look at the evidence and appropriate legislation in this tragic and difficult case for the best course forward. "
